Title
(EN) METHOD TO SECURE AN ELASTIC COMPONENT IN A VALVE
(FR) PROCÉDÉ DE FIXATION D'UN COMPOSANT ÉLASTIQUE DANS UNE VALVE
Abstract
(EN)
A valve comprises a flexible member including a slit formed on a central portion thereof and a first housing defining a first lumen extending therethrough, the first housing including a first contacting surface adapted, when the slit of the flexible member is aligned with the first lumen, to contact a first side of the flexible member the first housing defining a relief area extending about a perimeter of the first contacting surface radially outside the central portion relative to a longitudinal axis of the first lumen in combination with a second housing adapted to mate with the first housing with a second lumen defined by the second housing aligned with the first lumen and separated therefrom by the flexible member, the second housing including a second contacting surface.
(FR)
La présente invention concerne une valve comprenant un élément souple comportant une fente découpée dans sa partie centrale et un premier logement délimitant une première lumière se prolongeant au travers, ledit premier logement comprenant une première surface de contact conçue pour, lorsque la fente de l'élément souple est alignée avec la première lumière, entrer en contact avec un premier côté de l'élément souple, le premier logement délimitant une zone en relief se prolongeant radialement autour du périmètre de la première surface de contact à l'extérieur de la partie centrale par rapport à un axe longitudinal de la première lumière en association avec un second logement conçu pour s'accoupler avec le premier logement, une seconde lumière délimitée par le second logement étant alignée avec la première lumière et séparée de celle-ci par l'élément souple, ledit second logement comprenant une seconde surface de contact.
